CAT Scan-directed Stereotactic Brain Biopsy: With Template Produced by Computer Graphics

Summary

Stereotactic biopsy of inaccessible deep cerebral lesions based on and directed by the CT scan is a safe and effective method of biopsying cerebral lesions. It also has a potential for treatment of certain deep cerebral lesions and for Instillation of antibiotics, tapping cysts, etc. The coordinates for the stereotactic procedure may be obtained by measuring the location of the lesion on CAT scan of the head and inputting these measurements into special BASIC Computer program. The Computer printer makes a template which is superimposed on the lateral radiograph of the head with stereotactic frame in place, and the coordinates read off from the scales. The potential for possible stereotactic RF lesioning of deep brain tumors, after other methods have failed, deserves further investigation.
